<p>PROBLEM TO BE SOLVED: To provide a sanitary cleaning device which can use the same heater or controller even when the device is used in an area where the power supply voltage is different from that in Japan. SOLUTION: When the power supply voltage VIN is >=100 V ('Yes' in S1), the output of the heater 7 is calculated (S2) and the temperature of hot water TH is compared with a set temperature (S3). When the temperature of the hot water TH is lower than the set temperature ('No' in S3), the heater 7 is turned on with the output calculated in S2 (S4). When the temperature of the hot water TH is higher than the set temperature ('Yes' in S3), the heater 7 is turned off (S5). In addition, the water stored in a hot water storage tank is continuously maintained at the set temperature by always continuously performing the steps S3-S5. When, for example, the power supply voltage is 200 V, the duty ratio of the output of the heater 7 is calculated as 50% and, thereafter, the heater 7 is controlled with the output of 50%.</p> |
